The command of multiple photographing is performed with the operation means of the camera and the locking means is held in a locked state by a holding means even after completing the charging actions according to the command and the motor 1 is actuated by a control means while the holding means is actuated after completing film exposing actions.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a film winding device for a camera, and more particularly to a film winding mechanism for realizing multiple exposure photography.

[Conventional technology]

2. Description of the Related Art Hitherto, many high-class cameras that have been widely used, such as auto-focus cameras, generally have a multiple exposure function. There are various methods for realizing multiple exposure photography depending on the mechanism of the camera. In the case of the above camera equipped with an electric drive mechanism, there is generally a charging process for charging the aperture, mirror, shutter, etc.
Since the film winding process for winding the film is carried out sequentially and continuously by the motor, or the charging process and the film winding process are carried out simultaneously,
In order to perform multiple exposure, it is sufficient to use some means to separate the driving of the charge system and the film system, lock the film system mechanism, and drive only the charge system mechanism. The simplest way to think about such a mechanism is to install two motors and a charge system and film system drive transmission mechanism (generally called a two-motor system) in the camera. Multiple exposure photography becomes easily possible. Many of the above-mentioned cameras that have been provided conventionally employ such a mechanism. However, the problem with this mechanism is that, as mentioned above, two independent drive mechanisms are provided in two systems, which increases the cost and each mechanism occupies a large space inside the camera, which hinders the miniaturization of the camera. be.

[Problem to be solved by the invention]

Generally, as is well known, the operation of the above-mentioned camera during normal exposure is such that after completion of exposure, a charging process is performed, and then a film winding process is performed. Further, the film is stopped by a winding mechanism every time one frame is wound. Therefore, when performing multiple exposure, the charging process may be performed while continuing this state of film winding. Moreover, it is also possible to realize multiple exposure photography by using a single motor to drive each drive mechanism for the charge system and film system. In other words, the present invention has been made based on this point of view, and uses one motor to drive each mechanism of the charge system and film system, and when transferring the motor drive from the charge system to the film system, the film system If the winding mechanism that locks the mechanism continues to be in the winding state, it becomes possible to complete the charging operation without the film being wound up. In other words, it becomes possible to realize multiple exposure photography. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a film winding device that performs only a charge operation after release based on a predetermined command, and does not wind the film, thereby enabling multiple exposure photography.

[Means for solving the problem, and actions/effects] (Structure
In order to achieve the above object, the present invention was constructed as follows. That is, the camera film winding device of the present invention has 1
one motor, a film transport mechanism driven by the motor to transport the film, a charging mechanism driven by the motor to charge a predetermined mechanism, and either the film transport mechanism or the charging mechanism is locked. When a drive transmission mechanism transmits the drive of the motor to one of the other mechanisms, the charging mechanism is locked when the charging operation of the charging mechanism is completed, and the locking is released after film winding is completed. A locking mechanism, and a winding mechanism configured to lock the film transport mechanism each time one frame of film transport is completed during normal winding, and release the lock after the charging operation is completed; , an operating means that is operated when performing multiple exposure photography and commands multiple exposure operation; a holding means that holds the winding mechanism in a locked state even after the charging operation is completed according to a command from the operating means; and the holding means and control means for operating the motor during the operation of the motor and after the film exposure operation is completed. Note that the above-mentioned predetermined mechanism refers to mechanisms such as an aperture, a mirror, and a shutter. (Function) According to the above configuration, when the exposure is completed, the charging mechanism is already unlocked, and normally the motor is driven and the charging mechanism is activated first, and then the film transport mechanism is activated. It is driven to transport one frame of film. However, when the operating means is operated, that is, when a command to perform multiple exposure photography is issued, the winding mechanism is held in a locked state by the holding means, so that the motor is not driven. In this case, only the charging mechanism is operated and film transport is not executed. On the other hand, since charging of the predetermined mechanism is completed by the operation of the charging mechanism, film exposure operation is possible. In other words, multiple exposure photography is possible by operating the operating means. (Effects) As described above, since the present invention enables multiple exposure photography with one motor, the drive transmission system including the motor becomes more compact than the conventional two-motor camera. As a result, multiple exposure photography can be achieved at low cost and without requiring much space. Further, according to the camera film winding device of the present invention, multiple exposures can be performed using only an operating means for performing multiple M exposures, specifically, a switch button and an electric switch linked to the button. In other words, multiple exposure photography can be easily achieved by simply providing a changeover switch for creating multiple exposure modes.
